Introduction
This manual is for users of the Hampshire Company’s automatic touch screen and communication-detecting
TSHARC-10D, “Devil Ray” touch-screen controller board. The TSHARC touch screen controller and software
described within this document are assumed to be used with four, five or eight wire analog resistive touch screen
products manufactured by a variety of touch screen manufacturers. Touch screens between manufacturers vary with
regards to light transmission, sensitivity, contact resistance, capacitance and other electrical characteristics.
Because touch screen quality and electrical characteristics vary between touch screen technologies and
manufacturers, the actual, overall performance of the combined system will vary between touch screen overlay
manufacturers’ products. While Hampshire’s touch screen controllers and drivers improve the performance of low
quality or damaged touch screens, Hampshire does not guarantee the performance of, or recommend the use of, low
quality touch screen overlay products in any touch screen implementation.

NOTE
The board part number and version can be found on a label on the back side of the controller board. The firmware
revision may be found on a label or a laser mark located on the 28 pin TSHARC™ Micro-controller on the top side of
the controller board. Additional information is available about the labeling of Hampshire products.
Static Protection Warning
The TSHARC-10D controller has internal static protection to +/- 15kV for static discharge from the touch screen to the
controller. This static protection is adequate for most applications but is only effective once the board is grounded via
the mounting holes. In some applications, it may be necessary to protect the controller board from excess transient
voltage.
If you believe that your application will require additional static protection, it is up to you to determine the appropriate
static protection needed to protect your electronics from transient voltage. Failure to take the necessary
precautions may result in damage to your controller. Hampshire does not warrantee the TSHARC controller
board against transient static discharge damage.

Communication, Touch Screen and Power Connection Overview Diagram
The Devil Ray controller will automatically detect and configure itself for the communication and touch screen type
connected. The controller can differentiate between the industry’s two most common 4 and 5 wire touch screen pinouts as well as detect an 8-wire touch screen connection. In addition, it will automatically detect a USB or a serial
(RS-232) connection. This eliminates the need to configure the Devil Ray controller manually for any analog resistive
touch screen type or RS-232 or USB communications. Refer to Fig. 6.0 for the correct connection procedures.

Integrating the TSHARC™ Devil Ray controller
Mounting the TSHARC™ Devil Ray controller
Take special care to insulate the controller from system and display electronic EMI and RFI generating components.
Use conductive 4-40 stand-offs or ground lead wires terminated to the grounded system enclosure or PC board to
insure proper static protection and grounding. Sources for these are available on the website.
STANDOFFS MUST NOT TOUCH ANY PORTION OF THE CIRCUIT.
Locate the controller in a location that minimizes bending or creasing of the touch screen overlay connection tail.
The touch screen tail should not be creased. If it is necessary to crease the tail of the touch screen, check with the
touch screen supplier to insure that they will warrantee this type of integration.
Communication and power Connection at “H1”.
Optional USB header “H5”
Communication connector type Amp 1 x 8, .100, .024”sq., .230” mating length, friction lock header 640457-8 is
utilized to connect the controller to the computer for RS-232 or USB communication.
An optional 4 position USB connection may be mounted as identified in Fig. 8.0. Contact Hampshire for details about
ordering the controller with this connection configuration. Although Hampshire has taken steps to eliminate the
effects of EMI/RFI noise, using a shielded cable will help improve the performance of your touch screen system.
The TSHARC™ Devil Ray controller automatically detects RS-232 (9600 baud) and USB (HID compliant, low speed)
communication. While these are Hampshire’s standard communication formats, please contact Hampshire Company
for other communication speeds or formats that may be available for special applications
Power Connection
5vDC regulated power. Connect 5vDC regulated power to pins 1 and 2 at header position “H1”. Be careful to check

WARNING: SUPPLYING POWER FROM TWO DIFFERENT POWER SOURCES WILL PERMANENTLY
DESTROY YOUR CONTROLLER, YOUR COMPUTER, OR YOUR MONITOR.
If installing the TSHARC Devil Ray into a monitor application where the end user will decide to use USB
communication or RS-232 communication, the board must be powered internally. Because the board can not be
supplied with power from USB and internal 5v, it is recommended that the power (pin 1) contact be removed from the
USB socket to insure that multiple power source connections are not permitted.
Hampshire RS-232 and USB Communication Protocol
All Hampshire touch screen controllers communicate with the host computer via 4-byte (RS-232) or 5-byte (USB)
communication protocol. Hampshire’s 4-byte communication protocol produces the industry’s most reliable,
accurate data transfer information without compromising touch speed.

Elo™ and Microtouch™ Communication Options
Many Hampshire controllers may be configured to communicate with other industry protocols such as 3M’s 5-Byte or
Elotouch™ 10 byte, and Semtech™ communication protocol. It is important to note that the overall performance of
the Hampshire controller will be changed to that standard’s level of performance. Hampshire has device driver
software as well as TSHARC controller hardware products to help you migrate from a competitive product to a
Hampshire product.
In no case does Hampshire authorize the use of any driver software to enable a Hampshire controller without proper
authorization from the software developer or rightful owner of the software. Please contact your supplier to determine
if you may legally utilize that software.

Connect the Touch Screen (Header positions “H2” and “H3”)
Touch screen connector type: 2 x 8, .100”, .024”sq., .230” mating length, pin strip header. Sullins part number:
PTC08DBAN.
The TSHARC calibration software supplied with the controller must be run to map the touch screen to the display.
Auto detect 4, 5 and 8 wire touch screens connected to position “H2”, “H3”
The Devil Ray controller will automatically detect and configure to decode both industry standard 4-wire touch screen
pin-outs as well as both industry standard 5-wire touch screen pin-outs. It is important to connect the touch screen
to the correct set of pins. Connect your 4 wire, 5 wire or 8 wire touch screen to the controller as identified in the
diagram below. Once the controller is powered on, it will automatically configure itself for the touch screen
connected.
In order to enable the Devil Ray board to autodetect 4, 5, and 8 wire touch screens it utilizes an on board multiplexor
to decode three of the four sides of an 8 wire screen. The fourth side is decoded, but not through the multiplexor. In
rare cases, and on some inexpensive, low resistance 8 wire touch screens, you may need to enable the ratiometric
conversion on the fourth side of the screen. In this case, you may order the Devil Ray with 100% 8 wire ratio metric
functionality. However, you will not be able to autodetect 4 and 5 wire touch screen technologies once the board is
factory configured for exclusive 8 wire ratiometric conversion algorithms.
